本論文的主要目的在於提供LED光源投影機一可行的系統化設計方法。因此,本研究先經由WIPS軟體找出近年來與LED投影機相關之專利,依其內容進行分析,繪製其技術魚骨圖、功效魚骨圖及技術功效矩陣表,以得知目前該相關研究專利的發展趨勢,並選定一篇與該表中之技術或功效項目相關度最高的一篇專利作為標的,經由TRIZ理念的創新法則來找到改善之方法,再以該標的專利與改善後的創新模型進行專利的侵權迴避比對,最後以光學模擬軟體作為驗證及優化。本論文針對標的專利中改善了能源的浪費卻增加了裝置結構複雜度和操作困難度的缺點進行改善,依TRIZ矛盾矩陣表得到的發明法則,再經由TracePro光學模擬系統軟體模擬的結果,驗證了可藉由光源的改變搭配各種光學鏡片的組合與光路的設計,而達到增加該標的專利的效能並且可簡化其裝置結構。另外,藉由LED ARRAY光源與裝置間的優化模擬程序,可得到本創新模型最佳化效能之裝置結構。
The main purposes of the research provide a systematized design method of the LED projector. First, we search and analysis patents about LED projector recent years by WIPS. Then we design cause-and-effect diagram about the technology and efficient and technology efficiencies matrix to get the trend about LED projector patents and choose one as aim patent that much related with trend. To continue, we find the improve ways by TRIZ rule and compare between aim patent and innovation module to avoid infringement patent. Eventually, we prove and do best efficient by optical simulate software. The research focus on improving defects of the aim patent that improves the energy waste but complicates the device structure and operation. We use TRIZ contradictory matrix and TracePro optical simulation software to get better efficient and to simplify the device structure by light source change, optical device combination and optical path design. Moreover, we can get the best efficient of the device structure of the innovation module by optimizing the simulate procedure between LED Array and device structure.
